Owners will have to prove that their current pit bulls have been living in Montreal since before the October 3rd ban.

If the dog owner fails to follow the new rules, their dog will be seized and the owner will face a fine up to $4,000.

According to CTV News, pit bulls make up just less than five percent of the Montreal dog population, yet are responsible for nearly 38 percent of the city’s 137 serious dog-related injuries and deaths since the beginning of 2015.

The pit bull category includes all American pit bull terriers, American Staffordshire and Staffordshire terriers, and dogs that are mixed with any of the three breeds.
